Houston Texans running back Arian Foster had to be carted off the team's practice field on Tuesday after suffering a calf injury. Coach Gary Kubiak told reporters after organized team activities that Foster's injury is a strain. Per the Houston Chronicle, Foster had his calf treated with ice before he got assistance in leaving the field.

Receiver Andre Johnson told The Associated Press that he saw Foster limping off the field after a running play.

There was no word on how much action Foster will miss in the offseason with more than three months left before the start of the 2013 regular season. Given the wear he's endured as their workhorse the past three seasons, there's no reason for the Texans to rush him back when no games are being played.

"I think if it was real bad, I think we would've known about it by now. I don't think that it's (anything) real bad," Johnson told the AP.

Foster had a league-high 351 carries in 16 games in 2012, and had another 54 over two Texans playoff games. With his latest tweak, you can bet Houston officials will want to make sure he has the healthiest, freshest legs possible come September.
